To all whom it may concern:

Be it known that we, WILLIAM M. EsTEs, JOHN F. EsTEs, and JEssE E. SMITH, citizens of the United States, residing at Cullman, in the county of Cullman and State of Alabama, have invented a new and useful Cultivator Attachment, of which the following is a. speciiication. I

This invention has relation to fender attachments for cultivators and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide an attachment of the character indicated which may be easily and readily applied to the beam of a cultivator and. adjusted thereon and which is so constructed as to efiectually ward off the earth cas tup by the cultivator shovels and protect the standing plants from the same.

The fender consists of discus members mounted upon arms and which are adapted to move along the opposite sides of a row of plants, said arms being pivotally mounted and adapted to swing vertically and independently of each other so that the disks may rideover obstructions and cooperate in keeping each otherfree of trash and the like. The said arms are attached to ogee shaped. sides of a yoke which in turn is adapted to engage the cultivator beam as above indicated.

Figure 1 is a side elevation of the attachment applied to a beam, and Fig. 2 is a perspective view of the attachment with parts removed and parts in section.

The attachment consists of the yoke 1 which is provided with the parallel spaced ogee side portions 2, 2. The intermediate portion of the yoke 1 is adapted to lie under the beam of the cultivator bracket (indicated by 8 in the drawing) and the intermediate portions of the ogee extremities 2 are connected together bya crossbolt 4which passes through a perforation in the said cultivator beam. The rod 5 is located between the rear ends of the portions 2 of the yoke 1 and is provided at its opposite ends with the clamp nuts 6 which are adapted to engage the outer sides of the said portions 2. The sleeve 7 is mounted upon the rod 5 and bears at its ends against the inner sides of the portions2. The

arms 9 are pivoted at their forward ends upon the rod 5 and are provided at the lower edges of their forward extremities with the in wardly disposed lugs 9 which are adapted to lie under and engage the lower edges of the portions 2 of the yoke 1 whereby the pivotal movement of the arms 8 with relation to the said portions 2 is limited and when the said arms 8 are in their lowermost positions they are substantially in alinement with the rear extremities of the portions 2 of the said yoke 1. The disks 10 are journaledupon the arms 8. The arms 8 are laterally bent at intermediate points as at 12 in order to properly space the disks 10 apart.

From the foregoing description it is obvious that when the yoke 1 is placed upon a beam 3 so that its intermediate portion is under the beam and the bar 4 is over the beam that the weight of the rear end portions of the said yoke and the arms and disks carried thereby will cause the intermediate portion of the said yoke to bind against the beam with sufficient intensity to maintain its adjusted position upon the beam Without the aid of securing devices of a positive nature. When the yoke is so mounted and the disks 10 are moving along the opposite sides of the row of plants the said disks will protect the standing plants from the earth cast up by the cultivator shovels. Furthermore, should either one of the said disks encounter an obstruction it will ride over the same without elevating the other disk and should either one of the disks collect trash the other disk will elevate sooner or laterby meeting an obstruction and when it passes over the said obstruction and descends it will be liable to encounter the trash collected about the first said disk and free the disk of the trash. The advantage gained by having the contour of the members 10 circular or in the form of disks is that no angles are presented for the collection of trash or for tearing through the foliage of the standing plants. As the edges of the disks present nothing but obtund curves to obstructions, trash and the standing plants they tend to ride smoothly over the obstructions, minimize the collection of trash and avoid injury to the growing plants.
